An example of sound pressure sensing is an electret condenser microphone (electret coffee such as microphone), which is found in the mobile communication device of Xu Xi. & electret condenser microphones have been miniaturized to match. Mobile devices (such as mobile electronics and headsets typically have a diameter of 6 mm) and a door opening of 3 mm. A problem associated with these electret condenser microphones is that, because they are designed to vibrate with a medium sound, in addition to the voice signals of interest, they are also commonly referred to as 5 200425763% ambient noise. Therefore, the received voice message contains noise (e.g., engine, people, and wind), and most of the noise cannot be removed without lowering the sound quality f. As far as the various downstream audio processing devices of the main communication device are concerned (for example, including basic voice services and speech discrimination), the noise existing in the received voice signal causes significant quantitative and functional problems. Another device used for detecting instructions is a physiological loudspeaker, also known as "p ~ Mic". The body vibrations generated by Mie_Voice Lang are used by using the filling-less seam connected to the pressure vessel. Because the rubber pad is fully connected to human flesh and insufficiently connected to the air, p-Mic can accurately detect speech vibration when placed against the skin (even in high-noise environments). However, this solution requires a firm contact between the pad and the skin to function effectively (this is an unacceptable demand in the consumer market). Moreover, based on the size of about 5 inches on one side, p-Mic is usually too large for many consumer communication products. In addition, p-Mic is too expensive for widespread use in consumer products, such as headphones. Furthermore, p-Mic does not use a standard loudspeaker electrical interface, so that additional circuitry is required to connect the P-Mic to an analog-to-digital converter, thereby increasing both size and implementation cost. Yet another common device commonly used to detect speech, theoretically similar to P-Mic, is a bone conduction microphone (BCM). The BCM includes an accelerometer 'for measuring skin / meat vibrations produced by speech. β〇 [of the accelerometer measures its own displacement caused by speech vibration. However, more like p-Mic, the accelerometer requires good contact to operate effectively, and is currently too expensive and electronically bulky for use in commercially available communication products. Furthermore, the accelerometer cannot be used with a standard loudspeaker interface, so that additional circuitry is required to connect the accelerometer to an analog-to-digital converter, thereby increasing both size and implementation cost. 200425763 [Summary of the invention] (Effects of voice increase and noise suppression, voice coding, and other applications.-A kind of acoustic vibration transmission wire, also known as voice sense device, the system is as follows.

However, those skilled in the art will understand that the present invention can be implemented without such details. In other cases, it has been detailed The ground display money reveals the well-known structure and Wei, so as to avoid unnecessarily obscuring the description of the specific example of the present invention. Figure 1 is a cross-sectional view of the specific example of the acoustic vibration sensor _ (also referred to herein as a sensor). FIG. 2A is an exploded view of the acoustic vibration sensor of the specific example of FIG. 1. FIG. Fig. 2B is a perspective view of a specific example of the acoustic vibration sensor 100. The sensor 100 includes a shout body 102 having a first aperture 104 on a first side and at least one second aperture 106 on a second side of the housing 102. The diaphragm 108 (also referred to as a sensing diaphragm 108) is located between the first and second orifices. The connector 11 (also referred to as the cover no or cover 110) forms an acoustic seal around the housing 102, so that the first aperture 104 and the diaphragm side facing the first aperture 104 are self-speaking. The airborne sound environment is separated. A specific example of the connector 110 of 200425763 is continuous (but not limited to this). The second orifice ί06 connects the second side of the diaphragm to the external environment. The sensor also includes electret material 120 and related components, and electronic components that receive sound signals from the speaker through the connector 110 and the diaphragm 108 and convert the sound signals into electrical signals representing human voice. The electrical contact 130 provides an electrical signal as an output. For other specific examples, any type / combination of materials and / or electronic components can be used to convert sound signals into telecommunication signals that represent human voices and output electrical signals. The connector 11 of the specific example is formed using a material having an acoustic impedance conforming to the impedance of human skin (the characteristic acoustic impedance of the skin is about 1.5 × 10 06 Pa X s / m). Therefore, the connector 110 is formed using at least one material (but not limited to this) containing a lithone gel, a dielectric gel, a thermoplastic elastomer (τρΕ), and a rubber compound. As an example, the connector 11 of a specific example is formed using Kraiburg TPE products. For another example, the connector 11 of a specific example is formed using a Sylgard® silicone product. -The connection n 11G of the specific example includes a contact device 112 including, for example, nipple-like protrusions or protrusions protruding from one or both sides of the connector 11101. During operation, the contact device 112 protruding from both sides of the connector includes one side of the contact device 112 that is in contact with the speaker's skin surface and the other side of the contact device 112 that is in contact with the diaphragm (but this specific example is not limited to this.) limit). The connector and contact device 112 may be formed from the same or dissimilar materials. The connector (110) effectively transmits sound energy from the speaker's skin / meat to the diaphragm, and seals the diaphragm from the sound signal of the shouting air towel. Therefore, the connector with money contact device ιΐ2 efficiently Directly transmit sound signals from the speaker's body (voice vibration) to the diaphragm, while isolating the diaphragm 8 200425763

Therefore, the diaphragm 'reflects and / or emits many sound signals, and the sensor 100 mainly responds to the sound A transmitted from the speaker's skin (not working air). When placed against the speaker's head, the sensor m induces sound signals on the skin's surface, which greatly eliminates airborne noise signals, thereby increasing the signal-to-noise ratio and providing a very reliable source of voice information. 1. The use of a gasket between the diaphragm and the airborne environment of the speaker can enhance the sensor. _ Xiaoyue b male gasket is provided by the connector 11G. A modified gradient loudspeaker is used in the specific example because it has pressure orifices at both ends. Therefore, when the first hole 104 is sealed by the connector 110, the second hole 106 provides an exhaust hole through which air moves through the sensing H 1GG. FIG. 3 is a schematic diagram of a connector no of the acoustic vibration sensor 100 of the specific example of FIG. 1. The dimensions shown are in millimeters and are only intended as an example of a specific example. Other specific examples of the connector may have different structures and / or dimensions. The size of the connector 110 indicates that the acoustic vibration sensor 100 is small because the sensor 100 of the specific example is about the same size as a typical loudspeaker capsule seen in a mobile communication device. This small form factor allows the use of the connector 110 in highly mobile miniaturization applications, some of which include mobile phones, satellite phones, portable phones, wired phones, Internet phones, wireless transceivers, wireless communication radios, personal At least one of digital assistants (PDAs), personal computers (PCs), headphone devices, headsets, and headphones. Acoustic vibration sensors provide extremely accurate voice activity detection (VAD) in high-noise environments, including high-noise environments including airborne environments (if it is not greater than 9 200425763 voice amplitude measured using a full-range loudspeaker, then this is here The noise amplitude is larger). Accurate VAD provides significant performance and efficiency benefits in many important speech processing applications, including (but not limited to) noise suppression algorithms, such as Pathfinder calculations available from Aliph, Brisbane, California and disclosed in related applications Methods; speech compression algorithms, such as the Enhanced Variable Rate Encoder (EVRC) developed in many commercially available systems; and speech recognition systems. In addition to providing a signal with an improved signal-to-noise ratio, the acoustic vibration sensor operates with minimal power (e.g., about 200 microamperes). Compared to other solutions that require power, filtering, and / or significant amplification, the acoustic vibration sensor uses a standard loudspeaker interface to connect to the signal processing device. The use of a standard loudspeaker interface avoids the extra cost and size of the interface circuit in the host device, and supports sensors in highly mobile applications where energy use is a point of contention. FIG. 4 is an exploded view of the acoustic vibration sensor 400 according to another specific example. The sensor 400 includes a housing 402 having a first orifice 404 on a first side and at least one first orifice (not shown) on a second side of the housing 402. The diaphragm 408 is located between the first and second orifices. A layer of lithone gel 409 or other similar material is formed by contacting at least a part of the diaphragm. The connector 41o or the shield 410 is formed around the housing 402 or the silicone gel 409, and some of the connectors 41o are in contact with the silicone gel 409. The connector 410 and the silicone gel 409 together form an acoustic seal around the housing 402, so that the first orifice 404 and the diaphragm side facing the first orifice 404 are separated from the airborne sound environment of the speaker. The second orifice connects the second side of the diaphragm to the sound environment. As described above, the sensor contains additional electronic materials that can be suitably connected to receive a sound signal from the speaker via the connector 410, the stone gel 409, and the diaphragm 408, and convert the sound signal into an electrical signal representative of human voice. Another-specific example can be any combination of materials and / or 10 200425763 electronic components, to convert sound signals into electrical signals representing human voice. A specific example of the connector 410 and / or the gel 409 is formed using a material having an acoustic impedance conforming to the impedance of human skin. Therefore, the connector 41 is formed by using at least one material including, but not limited to, a silicone gel, a dielectric gel, a thermoplastic elastomer (TPE), and a rubber compound. The connector 410 efficiently transmits acoustic energy from the speaker's skin / meat to the diaphragm, and seals the diaphragm from ambient airborne sound signals. Therefore, the connector 41o efficiently transmits a sound signal directly from the speaker's body (voice vibration) to the diaphragm, while isolating the diaphragm from the sound signal in the airborne environment of the speaker. The diaphragm is isolated from the sound signal in the transmitting environment by the silicone gel 409 / connector 41〇, because the silicone gel 409 / connector 41〇 prevents the signal from reaching the diaphragm, thereby reflecting and / Or disperse the energy of many sound signals in the airborne environment. Therefore, the sensor 400 mainly responds to the sound energy transmitted from the speaker's skin, not the air. When placed against the speaker's head, the sensor 400 captures voice-induced sound signals on the surface of the skin, greatly eliminating airborne voice signals, thereby increasing the signal-to-noise ratio and providing a highly reliable source of voice information. There are many acoustic vibration sensors outside the ear to detect the position of the skin vibrations associated with speech production. The sensor can be installed in a device, earpiece or headset in any way, the only limitation of which is reliable skin contact with the skin-transmitted vibration associated with speech production. Fig. 5 shows a representative sensitive area 500-520 on a human head suitable for placing the acoustic vibration sensor 10_〇 in a specific example. Sensitive zones 500-520 include many locations 502 in the area behind the ear 502, 508, at least -location 512 in the area 510 in front of the ear, and many locations 522-528 in the ear canal area 52. The sensitive areas 500-52 on both sides of the human head are the same. These representative sensitivities 11 200425763 Areas 500-520 are provided by example only and are not limited to the specific examples used in these areas. FIG. 6 is a specific example of a universal earphone device 600 including acoustic vibration sensors 100/400 located at any of a plurality of positions 602-610. Generally speaking, the acoustic vibration sensor 100/400 can be placed on any part of the device corresponding to the sensitive area 500-52 (Figure 5) on the human head. Although the headset is shown as an example, any communication device known in the art can transmit and / or connect to the acoustic vibration sensor 100/400. FIG. 7 is a diagram of a manufacturing method of a specific example of a sound vibration sensor. For example, operation begins with a one-way loudspeaker 720 (at block 702). Silicone gel 722 and associated orifices are formed above / above the diaphragm (not shown) (at block 704). A material 724, such as a polyurethane film, is formed on or placed on the loudspeaker 720 / silicone gel 722 assembly (at block 706) to form a connector or shield.
